Armament
Apollo carried two QF 6-inch (152.4 mm) guns, one on the forecastle and the other on the poop and six QF 4.7-inch (120 mm) guns mounted in the waist. Four single QF 6 pounder Hotchkiss guns were carried in the waist, two more on the forecastle and two on the poop. Two 0.45 in (11 mm) Nordenfelt 5 barrel machine guns were mounted in the forecastle and two in the poop. One QF 3 pounder Hotchkiss gun was carried for use in the ship's boats, although it was provided one mount on each side of the after end of the waist. Four 14 in (360 mm) torpedo tube were fitted, two fixed on the stem and stern, and two broadside training tubes on the upper deck aft.
She was totally disarmed when she was converted to a minelayer in 1909 at Chatham Dockyard. Mine rails were fitted on her maindeck, which required that the cabins under the poop be removed, and she could carry a hundred mines. Her after deckhouse was extended and her magazines were converted to storerooms.
When World War I began she was given four QF 4.7-inch (120 mm) guns, but these were again removed when she was disarmed in 1915.
